Discover why copper shields outperform steel at low frequencies but steel dominates at high frequencies. This practical guide presents simplified formulas for calculating electromagnetic shielding effectiveness, revealing the surprising crossover point at 4200 Hz where material performance flips.

To determine a shielding material’s potential absorption loss capability, you must first know the frequency or frequencies of concern and, second, what shield materials you have available.

This tutorial article focuses on the skin depth phenomenon in good conductors. We begin with the uniform plane propagation, leading to the wave equations and their solutions in different media.
